Unlike a traditional car bumper, which has the sole purpose of protecting a vehicle in case of a collision, a step bumper is an accessory that offers additional purposes. It is an add-on replacement part for trucks. One of its functions is to ease accessibility in and out of the vehicle. True to its name, the part lets a person use it to step in or out of the truck. A step bumper also protects vehicles during low speed collisions, perhaps more so than an ordinary bumper. It can be made of aluminum, plastic, rubber, or other light metal. Plastic ones are manufactured with high strength polymers that make them nearly as strong as steel. While the plastic varieties work just as well, steel step bumpers are still on the market, and serve to add a tougher look to a truck if this is desired. In addition to protection, the part does add to the look of the vehicle on the front and back ends. Many drivers like to customize their trucks further once they have purchased them, and this is one accessory that truck-owners can use to personalize the look of their possession. Various colors are also available, popular ones being black, gray, silver, or chrome. These are important to match the bumper to the vehicle's color. If the owner is going to add one to beautify the truck, the right color is essential. Protection, customization, and replacement are important benefits, but this type of bumper also adds another function to vehicles. It adds more towing capacity to a truck. This is beneficial for road trips, especially nature trips, and even if the owner wants to use the vehicle as part of an automotive servicing business. Step bumpers are easily found on automotive sites and require mounting brackets for installation.
